SPECIFICATION forming part of Letters Patent No. 735,174, dated August4, 1903. Application led January 12, 1903. Serial No. 138,794. (Nomodel.)

To @ZZ whom, t may concern: p

Be it known that I, ROBBERT WHITLEY THWEATT, of Coppell, in the countyof Dallas and State of Texas, have invented a new and ImprovedRailway-Tie, of which the following is a full and eXact description.

My invention relates to the improvements in metallic railway-ties; andthe object of my invention is to produce a cheap, convenient, andsubstantial tie that may be firmly secured in the road-bed and whichwill hold the rails in such a manner that they cannotbe accidentallydisplaced.

My invention consists in a railway-tie, as hereinafter described andclaimed.

Reference is to be had to the accompanying drawings, forming a part ofthis speciication, in which similar figures of reference indicatecorresponding parts in all the views.

Figure 1 is a plan view of a tie embodying my invention. The dottedlines show where the rails cross the tie. Fig. 2 is a side View of thesame, showing the rails in recess and clamped down securely. Fig. 3 is acrosssection on the line m m, Fig. 2. Fig. 4 is a plan view of lip-headrail-clamp, with nut.

The tie 7 is provided with a broad base 8, which is adapted to restfirmly upon the roadbed, and has holes, as shown at 9, so that it may besecured with bolts or spikes upon a bridge.

The tie 7 has a thin center or bridge 10 eX- tending the full length ofthe tie and is provided on top with a rib 11 with iianges 12. Theiianges 12 are provided with a recess 13 which is the proper width anddepth to receive the base of rail, so when the clamps 14 are turnedaround over the base of the rail said clamp will hold rail securely, soit cannot be displaced. The Iianges 12 are provided with holes orperforations 15, disposed at opposite sides of the rail-receiving recess13. These holes are adapted to receive clamping-bolts 14, each providedat its upper end with a lip or linger which engages over the base of therail, and at its lower threaded end, beneath the iiange 12, with aset-nut, which bears upon said ange and is operable for drawing the bolt14 downward to clamp the rails securely in the recess 13 and maintain itfirmly in position upon the tie. This clamp 14, Fig. 4," may be put inthe tie at the factory, with the lip turned on a line with the edge ofthe recess 13 and the nut secured down taut, and when the rail is placedin the recess 13 it only requires a stroke with the hammer to turn thelip around over the base of the rail, forming a perfect clamp for therails. The holes 15 are to be used for additional rail-clamps, if foundnecessary.

From the foregoing description it will read.- ily be seen that the railmay be quickly and easily secured to the tie.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- The combination with a tie comprising a base, a headand a connecting-web, of a rail supported by the tie, said tie beingprovided at the point of intersection of the rail with a rail-receivin grecess and lateral flanges, the latter having perforations disposed atopposite sides of the rail, and clamping-bolts extended through saidperforations and provided at their upper ends with lips or lingersengaging over the base of the rail and at their lower ends each with anut bearing beneath the flange and operable for drawing the boltsdownward to clamp the rail securely in the recess.

In testimony whereof I have signed my name to this specification in thepresence of two subscribin g witnesses.

ROBBERT WHITLEY THWEATT.
